Abstract

Background Central line–associated bloodstream infection (CLABSI) is a complication of central venous access devices used for parenteral nutrition (PN). PN overfeeding is associated with increased adverse effects; however, whether risk for CLABSI is influenced by PN dosing is uncertain. Objective The purpose of the study was to assess differences in CLABSI risk associated with recommended total energy dosing in hospitalized adult patients receiving PN. Methods A case-control study was conducted in a single United States Veterans Health Administration health system to assess the potential CLABSI risk factor of weight-based PN kilocalorie dosing. Hospitalized adult patients who developed CLABSI while receiving PN were identified and compared to a control group of patients who did not develop CLABSI. The exposures evaluated were overfeeding, defined as greater than 30 kcal/kg/day, and underfeeding, defined as less than 20 kcal/kg/day. Results Twenty-nine cases of CLABSI were identified and compared with 274 controls. Odds of CLABSI were significantly higher in patients receiving greater than 30 kcal/kg/day (OR, 3.63; 95% CI, 1.55-8.48; P < .01). No significant difference in odds was found for patients receiving less than 20 kcal/kg/day (OR, .74; 95% CI, 0.21-2.57; P = .63). Conclusion Increased risk for CLABSI in hospitalized adult patients receiving PN was found to be associated with overfeeding, but not underfeeding. These results may aid clinicians in the management of patients requiring PN and in the generation of hypothesis for future investigations.
